Underlayments are optional and used just below the floor covering and above the sub Floor, here we are planning to use a laminated subfloor.

Subfloor is placed just above the joist and offers the real strong base for the top floor covering and it must be strong enough to bear all types of weight.

Learn how to prepare Laminate subfloor.

1: Have a laminated plank that is larger in size, usually manufacturers offer 4*8-foot sheets.

2: Subfloor is the main area that bears the maximum weight hence the thickness of the plank should be at least 5/8″.

3: Now use the measuring tape and measure the spacing in between studs of the joist support, as we need to make sure our plank will be laid exactly on top of the joist.

4: Make sure each of the planks is covering at least 2-3 support of the joist that strengthens the subfloor and improves its capacity to bear the load.

5: After measuring, draw the same lines on the laminated plank as that will give us an idea of where exactly we need to screw on top of the plank.

6: All the measurement is ready, hence we will start first from the corner of the wall which form 90 degree angle and make sure you placing the laminated plank perpendicular to the joist.

7: Now use an Adhesive subfloor glue on top of the joist support that will reduce the chance of squeak noise and offer better joints against the joist.

8: Now place the first plank start from the corner and make sure it aligned perfectly and covering min 2-3 spacing of the joist.The end of the plank should be at the exact centre to the support of the joist.

9: Now place another plank in the same raw until you reach the wall on the opposite side of the first wall or finishes the completely raw, last plank may require to cut to a small size.

10: Make sure to have a spacing of at least 1/2″ in between each plank, as it offers the ability to shrink and expand in different climate situations.

11: Now, if you are comfortable enough then start putting the laminated plank beside the existing one and in the second raw and finish the same raw.

12: Again make sure to maintain the 1/2″ spacing in between both raws and if possible place the second raw 2 planks in such a way that it joints at the exact center of the first raw of any plank and all three has 1/2″ spacing.

13: Now if you have a perfectly laid out plank in both raws, then this time is to drill the plank against the joints using the nails and make sure you use the drawn line of plank for exact drilling the nails against the joist.

14: Continue the same pattern of the placement of the laminated plank and I am sure the last plank in each raw will require a different size.

15: Cut the plank using the available saw for the required measured exact size and place it to the exact place and screw this as well.

16: Once you are finished with placement, make sure none of the planks are left for screw and covered complete area and use a hammer to fix any nails which are not drilled perfectly.

17: If you have found unevenness on the subfloor now place underlayment on top of the subfloor.

18: Place the underlayment start from the corner side and they are adhesive in nature so you can stick the ending of one with the other.

Continue till the complete area is covered and now you have a beautiful laminated subfloor ready to lay down vinyl flooring.
